Installation

Hello World

This basic example creates a TextView titled "Hello, World!" and displays it in your terminal:

package main

import (
	"gitlab.com/tslocum/cview"
)

func main() {
	app := cview.NewApplication()
	
	box := cview.NewTextView()
	box.SetBorder(true)
	box.SetTitle("Hello, world!")
	box.SetText("Lorem ipsum dolor sit amet")
	
	app.SetRoot(box, true)
	if err := app.Run(); err != nil {
		panic(err)
	}
}

Examples are available via godoc and in the "demos" subdirectory.
